Twenty-one million people have a master’s degree in the U.S., as of the year 2018. That number has doubled since 2000 when just over 10 million people held this degree, according to data from the U.S. Census.

To earn a master’s degree, the first step for many students is to take GRE. The GRE is the entrance exam for graduate school, similar to the SAT or ACT being the entrance exam for a bachelor’s degree.

What’s on the GRE?

The GRE evaluates a student’s readiness for graduate-level education. The test has three sections: Analytical Writing, Verbal Reasoning, and Quantitative Reasoning. This timed test is adaptive, which means your score in previous sections influences the difficulty of upcoming questions. The test takes almost four hours to complete and is administered at a testing center.

How is the GRE scored?

The grading of tests like the GRE can be complicated, but this particular test is scored in one-point increments on a scale of 130-170. The Analytical Writing section is scored separately by a computer and by a human on a scale of 0-6. 

Why do you need a GRE prep course?

For students or parents considering a GRE prep course, there are several reasons to go through with one. Here’s a look at why people opt for a prep course: 

Elevate your score

To get into the school of your choice, students might need to achieve a certain test score. To do so, a prep course is the best way to go. 

Explore your graduate school choices and know what kind of score you need before selecting any prep course. It’s important to have a goal in mind.

Get a refresher

For people who want to return to school after being out in the workforce for a while, a prep course is ideal. The course can help people get reacquainted with standardized testing and provide the most up-to-date course materials to succeed. 

Know what the test is testing

A prep course helps people know what the test is looking for and how the test is set up to do that. Learning the test’s structure, kinds of questions, and what it feels like to take a timed test is all part of doing well on the real exam. 

Materials are all in one place

There are free GRE resources online or books that can be borrowed from a library, but prep courses are designed to offer high-quality study materials that are in one place. Rather than scouring the internet for practice exams or study guides, it’s easier to log into one portal and work through ready-made material.

Who needs a GRE prep course?

For students wondering if a prep course is right them, here’s who typically takes the courses: 

Students looking to score well

Whether your dream school requires a certain test score or you just want to do well to have as many options as possible, a prep course is for you. 

Students who struggle with tests

There are some students who simply aren’t good test-takers. Rather than shy away from this test, students who get test-day jitters say preparing for the exam calms their anxiety and gives them a chance to focus on the task at hand. 

Students who are willing to do the work

Prep courses require students to set aside time to study. Attending classes is part of the process, but working at home is part of the process too. 

Things to consider before selecting a GRE prep course

When you’re ready to select a GRE prep course, here’s what to consider: 

Commitment level

To get the most out of a prep course, students have to put in the work. Going to class or attending an online course is just the start, students will have homework and will need to study. 


A prep course takes time, so students with busy schedules may need to make changes to accommodate prep courses. It might mean better time management skills or it might mean eliminating an extracurricular activity.

In-person or online courses

There’s a variety of GRE prep courses available. Some are scheduled, in-class courses with homework assignments that could last up to ten weeks, others are online and give students the chance to learn at their own pace. Students can also opt for private tutoring sessions as one of their prep options. 


The cost of prep courses varies. There are some free online resources that students enjoy and there are professional companies that specialize in prep courses. Courses can be expensive, some up to $2000. However, the average cost is usually around $500.

How to choose a GRE prep course

There’s a lot of test prep resources out there, but for those who are ready to commit to a prep course, here’s what you should look for: 

Look for a point improvement guarantee

If a school you want to attend requires a certain score for entrance into a graduate program, consider finding a course that guarantees a score improvement. The best score improvement guarantee that we found was seven points. 

Focus on the format

How do you prefer to learn? Whether you’re looking for in-person classes, online courses, classes with a set schedule or self-paced materials to work through – know what you want before you start researching. 

Experienced teaching

To get the most out of courses, look for ones with experienced teachers. Some courses are led by teachers who took the GRE and scored in the top 1% with other courses that don’t specify what credentials their teachers have. 


As with any test preparation course, students must evaluate the cost. It’s not always easy to weigh the cost of the course against the materials that are offered, but after researching several options students should be able to do a fairly good comparison. 

There are some reasonable courses out there for less than $100, but there are also courses that are $1000+. 

All of the prep courses are pretty clear about their plans and pricing. Students can easily find this information on the company website. 

Trial period

One of the best ways to find a course that’s right for you is to try a few. Many of the courses offer some sort of trial period. Take some time to try a platform or two and see which ones resonate best with you.
